In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 1483-55-2 as follows. Recommanded Product: 2-Bromo-5-(trifluoromethyl)benzonitrile
To a solution of 2-bromo-5-(trifluoromethyl)benzonitrile (10.0 g, 40 mmol) in dichloromethane (100 mL) was dropwise added a 1.0 M solution of diisobutylaluminum hydride in hexane (48 mL). The resulting solution was stirred under nitrogen at ambient temperature for 1 h and was then diluted by addition of ether (100 mL). After cooling in an ice bath, a 3 N solution of HCl was carefully added, and the mixture was vigorously stirred at ambient temperature for 15 min. The organic layer was washed with brine, dried (MgSO4) and evaporated. The resulting oil was purified by flash chromatography (5% EtOAc/hexane) affording 5 g of 2-bromo-5-trifluoromethylbenzaldehyde. 1H NMR (CDCl3) delta 10.39 (s, 1H), 8.18 (d, J=2 Hz, 1H), 7.82 (d, J=8.8 Hz, 1H), 7.70 (dd, J=8.5 Hz, 2 Hz, 1H).
According to the analysis of related databases, 1483-55-2, the application of this compound in the production field has become more and more popular.
